As per title.
I have a PowerColor Vega 64. Every now and then the screen goes black for a couple seconds, which drives me mad. The system doesn't hang like in other cases described in this forum, everything goes back to normal after a few seconds. It happens occasionally, let's say once or twice per hour, regardless of the game I'm playing.
My specs:
Vega 64
Z170 ASUS Sabertooth Mark 1
I7 6700K @ 4.6GHz
16GB DDR4 3200
600W Corsair PSU
Win10 64
IIyama GB276QSU 27" FreeSync
I game with FreeSync and Vsync enabled if that matters. Win10 is up to date, latest AMD driver installed too.
